Recently, dielectric elastomer actuators (DEAs) have been adopted to tune liquid membrane lens, just like ciliary muscles do to the lens in human eye. However, it faces some challenges, such as high stress, membrane puncture, ...

Common drivers of flapping wings are a motorized crank mechanisms, which convert the motor rotation into wing reciprocation. Energetic efficiency of the motorized wing flappers can be quite low due to the lack of elastic ...

Though capable of generating a large strain, dielectric elastomer actuators (DEAs) generate only a moderate actuation stress not more than 200kPa, which seriously limits its use as artificial muscles for robotic arm. ...

Electrical breakdown of dielectricelastomer actuators (DEA) is very localized; a spark and a pinhole (puncture) in dielectric ends up with short-circuit. This letter shows that prevention of electrothermal breakdown helps ...

A soft tunable lens with integrated dielectric elastomer actuator (DEA) can act like an eye lens to tune the distance of focal point. It has potentials to replace multiple hard lenses for cameras’ autofocus. The tunable ...

Rolled dielectric elastomer actuators (DEAs) are subjected to necking and non-uniform deformation upon pre-stress relaxation. Though rolled up from flat DEAs, they performed much poorer than the flat ones. Their electrically ...

Rolled dielectric elastomer actuators (DEA), which are prepared by rolling up a flat dielectric elastomer , are subjected to non-homogenous deformation and thus does not perform as well as the flat ones. Typically, the ...

Despite being capable of generating large strains, dielectric elastomer actuators (DEAs) are short of strength. Often, they cannot produce enough stress or as much work as that achievable by human elbow muscles. Their ...

Dielectric elastomer actuators (DEAs) are prone to failure by pull-in instability. However, this work showed that DEAs, which were immersed in a silicone oil bath (Dow Corning Fluid 200 50cSt), can survive the pull-instability ...

This letter reported that a dielectric elastomer actuator (3M VHB), which is immersed in a liquid dielectric bath, is enhanced tremendously in dielectric strength up to 800 MV/m, as compared to 450 MV/m for the actuator ...
